Sunlight is often associated with skin cancer and harmful UV-radiation. Though a genuine concern, it negates the importance of natural light in our lives and general wellbeing. Small and moderate exposure to sunlight has positive health benefits.
Vitamin D plays a vital role in stopping and slowing down the overproduction of cells which often cause tumours. We can get Vitamin D from various food types such as liver, eggs, and fish. However, 90 percent of Vitamin D comes from exposure to sunlight. Therefore, to get sufficient supply of the sun, our houses should have windows to let in rays from the sun. However, some corners may never get any light from the sun. Good news is there is a way to distribute natural light into the interior of the house. With the use of fibre-optic technology natural light can be filtered throughout a 30-floors building.
Vitamin D is linked to bone health. Therefore, to avoid bone diseases, and muscle weakness you need a sufficient supply of Vitamin D from the sun. Vitamin D is known to increase the absorption of calcium into the bloodstream which is responsible for healthy bones and teeth.
Lack of sunlight can cause seasonal affective disorder (SAD) a type of depression. Exposure to the sun increases the production of serotonin in the brain which acts as an antidepressant. It relieves various forms of depression. Artificial antidepressants work by controlling the levels of serotonin which is a mood-lifting chemical. With moderate exposure to the sun, you won’t need those antidepressants.
Apart from healthy bones and reduced risk of cancer, sunlight minimises the risk of diseases and disorders. Some common illnesses include multiple sclerosis, arthritis, and hypertension. Therefore, spending some few hours in the sun reduces a myriad of health risks. It can even promote weight loss.
